Endoscopic ultrasonography for staging depth of invasion in early gastric cancer: A meta‐analysis

Abstract

Endoscopic ultrasonography only has a relatively low accuracy for staging the depth of invasion in EGCs. Accordingly, EUS may be not indispensable in the staging of EGCs.

Endoscopic ultrasonography compared with multidetector computed tomography for the preoperative staging of gastric cancer: a meta-analysis

“…However, the standard imaging modality for clinical assessment of EGC remains debatable. Whether EUS is more accurate than MDCT in diagnosing EGC remains unknown [12, 15, 25]. This meta-analysis demonstrated that the sensitivity of EUS was significantly higher than that of MDCT for EGC, indicating that EUS was a preferred imaging modality in diagnosing EGC.…”

Diagnostic group classifications of gastric neoplasms by endoscopic resection criteria before and after treatment: real-world experience

“…A recent study [29] also showed that EUS may not be necessary before ESD, because EUS did not increase the likelihood of selecting the appropriate treatment in differentiated-type EGC. One recent meta-analysis also concluded that EUS may be not indispensable in the staging of EGCs [30]. Pit patterns observed by magnifying chromoendoscopy can be used to predict invasion in colonic lesions [31].…”

Validation of the prognostic impact of the new tumor-node-metastasis clinical staging in patients with gastric cancer

“…However, the overall diagnostic accuracy rate was 70% or lower and the sensitivity of T4 diagnosis was 48%. Most Japanese studies on the usefulness of EUS aimed to determine the indication for endoscopic submucosal dissection and, therefore, mostly covered early gastric cancer patients [28,29]. Evidence on the usefulness of EUS for determining cancer depth in T2-T4 cases remains limited.…”
